Entering the
RXTOT
command without a parameter displays the timer
value in minutes. Entering the
RXTOT

ranging from 1 to 1440 resets the timer in minutes. Entering the
RXTOT

NONE
disables the timer. The default value
is
NONE
.
Soft-Carrier Dekey
SCD [0-255]
The “soft-carrier dekey” command sets or displays the amount of time
to wait after a de-key request before actually de-keying the radio’s trans-
mitter.
Entering the
SCD
command without a parameter displays the timer value
in milliseconds. Entering the
SCD
command with a parameter ranging
from 0 to 255 resets the timer in milliseconds. The default setting is 0,
which means that the radio de-keys immediately following removal of a
keying signal
(
see “Simplex and Switched Carrier Operation” on
Page 4
).
If you experience problems with repeater operation after changing the
CTS
,
PTT,
or
SCD
values, contact GE MDS Technical Support.
